# L2 Message Implementation Status
|
|
|
|
## ✅ COMPLETED IMPLEMENTATION
|
|
|
|
### 1. L2 Message Types and Structures (`pkg/arbitrum/types.go`)
|
|
- **L2MessageType**: Enum for different message types (Transaction, Batch, State Update, etc.)
|
|
- **L2Message**: Complete message structure with parsed transaction data
|
|
- **ArbitrumBlock**: Enhanced block with L2-specific information
|
|
- **DEXInteraction**: Structured DEX interaction data
|
|
- **RetryableTicket**: Arbitrum retryable ticket support
|
|
|
|
### 2. L2 Message Parsing (`pkg/arbitrum/parser.go`)
|
|
- **L2MessageParser**: Full parser for Arbitrum L2 messages
|
|
- **DEX Protocol Detection**: Supports UniswapV3, SushiSwap, Camelot (Arbitrum native)
|
|
- **Function Signature Parsing**: Decodes swap functions (exactInputSingle, swapExactTokensForTokens)
|
|
- **Batch Transaction Processing**: Handles batch submissions with multiple transactions
|
|
- **Significance Filtering**: Identifies large swaps worth monitoring
|
|
|
|
### 3. Enhanced Arbitrum Client (`pkg/arbitrum/client.go`)
|
|
- **L2 Message Subscription**: Real-time L2 message monitoring
|
|
- **Batch Subscription**: Monitors batch submissions to L1
|
|
- **Retryable Ticket Parsing**: Handles cross-chain transactions
|
|
- **Arbitrum-Specific RPC Methods**: Uses `arb_*` methods for L2 data
|
|
|
|
### 4. Enhanced Monitor (`pkg/monitor/concurrent.go`)
|
|
- **Dual Processing**: Both traditional blocks AND L2 messages
|
|
- **Real-time L2 Monitoring**: Live subscription to L2 message feeds
|
|
- **Batch Processing**: Handles batched transactions efficiently
|
|
- **DEX Interaction Detection**: Identifies profitable opportunities in real-time
|
|
|
|
### 5. L2 Gas Optimization (`pkg/arbitrum/gas.go`)
|
|
- **L2GasEstimator**: Arbitrum-specific gas estimation
|
|
- **L1 Data Fee Calculation**: Accounts for L1 submission costs
|
|
- **Priority Fee Optimization**: Dynamic fee calculation for fast inclusion
|
|
- **Cost vs Speed Optimization**: Multiple optimization strategies
|
|
- **Economic Viability Checks**: Compares gas costs to expected profits
|
|
|
|
### 6. Comprehensive Testing (`pkg/arbitrum/parser_test.go`)
|
|
- **Unit Tests**: Complete test coverage for parsing functions
|
|
- **Mock Data Generation**: Realistic test scenarios
|
|
- **Performance Benchmarks**: Optimized for high-frequency processing
|
|
- **Error Handling**: Robust error scenarios
|
|
|
|
## 🚀 KEY IMPROVEMENTS IMPLEMENTED
|
|
|
|
### Real-time L2 Message Processing
|
|
```go
|
|
// Before: Only monitored standard Ethereum blocks
|
|
func (m *ArbitrumMonitor) processBlock(ctx context.Context, blockNumber uint64)
|
|
|
|
// After: Full L2 message processing pipeline
|
|
func (m *ArbitrumMonitor) processL2Messages(ctx context.Context)
|
|
func (m *ArbitrumMonitor) processBatches(ctx context.Context)
|
|
```
|
|
|
|
### DEX Protocol Support
|
|
- **Uniswap V3**: Complete support including multi-hop swaps
|
|
- **SushiSwap**: V2 style swap detection
|
|
- **Camelot**: Arbitrum-native DEX support
|
|
- **Extensible**: Easy to add new protocols
|
|
|
|
### Gas Optimization for L2
|
|
```go
|
|
// L2-specific gas estimation with L1 data fees
|
|
type GasEstimate struct {
|
|
GasLimit uint64
|
|
MaxFeePerGas *big.Int
|
|
L1DataFee *big.Int // Arbitrum-specific
|
|
L2ComputeFee *big.Int
|
|
TotalFee *big.Int
|
|
Confidence float64
|
|
}
|
|
```
|
|
|
|
## 📋 NEXT STEPS RECOMMENDATIONS
|
|
|
|
### 1. **IMMEDIATE DEPLOYMENT READINESS**
|
|
```bash
|
|
# Test the enhanced L2 monitoring

|
|
ws_endpoint: "wss://arb-mainnet.g.alchemy.com/v2/YOUR_KEY" # For real-time data
|
|
|
|
bot:
